Answer:
The Second One or B. You were correct.
Step-by-step explanation:
The associative property is when the numbers of an equation stay the same, but the parentheses move.
Answer:
Below.
Step-by-step explanation:
With replacement the sample space is:
(RR), (GG), (BB), (RG), (RB), (GR), (GB), (BR), (BG).
Without replacement you will not get 2 of the same colour, so it is
(RG), (RB), (GR), (GB), (BR), (BG).
Answer:
x = 2.5 or -0.8
Step-by-step explanation:
Here, we are to use completing the square method to solve for the values of x
Firstly, we divide through by 4
= x^2 -7/4x -2 = 0
Now, we move the two term to the right hand side
x^2 -7/4x = 2
Now, we divide the coefficient of x by 2 and square it;
That would be;
(-7/4 * 1/2)^2 = 49/64
we now add this value to both sides of the equation
x^2 -7/4x + 49/64 = 2 + 49/64
The right hand side can be rewritten as;
(x-7/8)^2 = 177/64
taking the square root of both sides
x-7/8 = √(177/64)
x = 7/8 ± √(177/64)
x = 7/8 + √(177/74) or 7/8 - √(177/64)
= x = 2.53802 or -0.788017
Which to the nearest tenth is
x = 2.5 or -0.8
Answer:
The answer is 600000
Step-by-step explanation:
"kilo" means 1000, so you add 3 zeros in the end. Hope this helped!
<span>The answer is 60.
Explanation<span>:
In mathematics, the word "of" indicates multiply. This means we would multiply 2/3 * 90.
We can write 90 as a fraction by putting it over 1, which gives us 2/3(90/1).
To multiply fractions, we multiply straight across: (2*90)/(3*1) = 180/3 = 60.</span></span>
